Description

Technical Field

[0001] This application relates to the field of bridge engineering technology, and in particular to a method and apparatus for assessing the technical condition of ancillary facilities of long-span bridges. Background Technology

[0002] From the perspective of current standards, the mainstream bridge structure technical condition assessment standards at home and abroad all take visual inspection data as the core and adopt a hierarchical comprehensive assessment method. However, they do not clearly define the assessment scope, classification standards and assessment methods for the ancillary facilities of long-span bridges, resulting in assessment "blind spots" in actual assessment. At the same time, the existing standards do not establish a progressive logic of "sub-facility components - sub-facility systems - sub-facility systems - overall ancillary facilities", and the scoring relies on subjective visual inspection and does not quantify the impact of the degree of deterioration and the number of components.

[0003] From the perspective of the shortcomings of the current methods, the document clearly points out that the current assessment of long-span bridges only refers to the appearance test data, lacks the support of multi-source data such as inspection and maintenance, and has not formulated specific assessment indicators and weights for ancillary facilities. In addition, the "Technical Standard for Urban Bridge Maintenance" (CJJ 99) even only divides Class I bridges into two levels of "qualified and unqualified", which cannot refine the maintenance requirements corresponding to the degree of deterioration of ancillary facilities. Summary of the Invention

[0004] In view of this, this application proposes a method for assessing the technical condition of ancillary facilities of long-span bridges, comprising the following steps: Based on the preset classification and grading standards for ancillary facilities, the components of each sub-facility are inspected, and the score of each sub-facility is obtained through preset calculation rules. The scores of each sub-facility system are calculated by combining the scores of each sub-facility system with the preset sub-facility weights to obtain the sub-facility system scores. The overall score of the ancillary facilities is obtained by calculating the scores of the sub-facilities and the preset sub-facilities weights. By comparing the scores of each sub-facility system, the sub-facility system scores, and the overall scores of ancillary facilities with the preset technical condition assessment standards, the corresponding level of technical condition is obtained.

[0005] In one possible implementation, based on a preset classification standard for ancillary facilities, the components of each sub-facility are inspected, and the score of each sub-facility system is obtained through preset calculation rules, including the following steps: According to the preset classification and grading standards, the ancillary facilities are precisely divided into four major categories of sub-facilities: protective facilities, transportation facilities, landscape facilities and other facilities. Each sub-facility system is then further subdivided into several sub-facilities. Using testing equipment and tools, the components of each sub-facility are tested to obtain component testing data; Substitute the component inspection data into the preset calculation rules, combine the component score, inspection index deduction value, minimum component score value and quantity coefficient, and calculate according to the formula. and The scores for each sub-facility system were calculated, among which For ancillary facilities i Technical condition rating of sub-facility systems; For the first i Sub-facilities j The rating of each component; For the first i Sub-facilities j The deduction value for each component's corresponding testing index; For the first i The lowest score among the components in the sub-facility category; This is a coefficient that varies with the number of components.

[0006] In one possible implementation, the process of calculating the sub-facility system score by combining the score of each sub-facility system with a preset sub-facility weight includes the following steps: Obtain the weight values ​​of each type of sub-facility in its respective sub-facility system from the preset weight database; Multiply the score of each sub-facility system by the corresponding weight of each sub-facility system; Summing the results of multiplication operations on all sub-facilities under the same sub-facility, according to the formula... The system scores are obtained by sub-systems, among which The technical condition of the ancillary facilities and sub-facilities is scored. The weight of each type of sub-facility within its respective sub-facility system.

[0007] In one possible implementation, the process of calculating the overall score of the ancillary facilities by combining the sub-facility system score with preset sub-facility weights includes the following steps: Obtain the pre-defined weight data of each sub-facility system within the entire ancillary facility system; Multiply the score of each sub-facility system with the corresponding weight of each sub-facility; Summing the results of multiplication operations on all sub-facilities according to the formula The overall score for ancillary facilities is obtained, among which Rate the technical condition of ancillary facilities; For the first i Technical condition rating of the ancillary facilities system; For the first i The weight of the ancillary sub-facilities system within the entire ancillary facilities.

[0008] In one possible implementation, the technical condition level is obtained by comparing the scores of each sub-facility system, the sub-facility system scores, and the overall score of ancillary facilities with a preset technical condition assessment standard, including the following steps: The technical condition assessment standards for each sub-facility system, sub-facility system, and ancillary facilities are obtained from the assessment standard database. The scores of each sub-facility system, the scores of the sub-facility system, and the overall scores of the ancillary facilities are compared with the score ranges of the corresponding levels. Based on the comparison results, the technical condition level of each sub-facility system, sub-facility system, and ancillary facility as a whole is determined.

[0009] One possible implementation also includes the following steps: Establish a dedicated database to store the testing data of each sub-facility component, the data of the scoring process at each level, and the final evaluation results. Classify and organize the stored data, and set index tags to facilitate subsequent queries and retrieval; Regularly back up the database to ensure data security and integrity and prevent data loss.

[0010] This application also provides a device for assessing the technical condition of ancillary facilities of long-span bridges, including: The inspection data acquisition module is equipped with a variety of devices adapted to the inspection of components of long-span bridge ancillary facilities, used to acquire raw component inspection data; The calculation and processing module is used to receive component inspection data from the inspection data acquisition module, calculate the score of each sub-facility system according to preset rules, and then perform subsequent score calculations at each level in combination with weights, and finally complete the determination of the technical condition level at each level and output the evaluation results. The data storage management module establishes a dedicated database to store the detection data of each sub-facility component acquired by the detection data acquisition module, the data generated by the calculation and processing module during the scoring process at each level, and the final evaluation result data.

[0011] In one possible implementation, the detection data acquisition module includes: The testing equipment integration unit is used to organically integrate various testing equipment; The preliminary data processing and transmission unit is used to perform structured processing on the raw detection data acquired by the detection equipment, that is, to package it according to a specific data format, and then transmit the processed data to the computing module quickly and stably through wired or wireless data transmission channels.

[0012] In one possible implementation, the computation processing module includes: The hierarchical classification calculation unit, based on the preset hierarchical classification standards for ancillary facilities, divides the ancillary facilities into four major categories of sub-facilities: protective facilities, transportation facilities, landscape facilities, and other facilities, and further subdivides them into several sub-facilities. The sub-facilities system scoring calculation unit receives component inspection data from the inspection data acquisition module and calculates the score of each sub-facilities system according to the preset calculation rules, combined with component scores, inspection index deductions, minimum component scores, and quantity coefficients. The hierarchical summary calculation unit first multiplies the scores of each sub-facility system with the preset weights of each sub-facility, and then sums the calculation results of all sub-facility systems under the same sub-facility to obtain the sub-facility system score. Then, it multiplies the sub-facility system score with the preset sub-facility weights and sums them to obtain the overall score of the auxiliary facilities. The rating unit retrieves the overall technical condition assessment standards for each sub-facility system, sub-facility system, and ancillary facilities from the assessment standard database, compares the scores of each level with the corresponding score ranges, and determines the technical condition level corresponding to each level based on the comparison results.

[0013] The beneficial effects of this invention are: By clearly defining the hierarchical classification boundaries of ancillary facilities from "sub-facilities – sub-facilities – sub-systems – overall ancillary facilities", constructing a hierarchical quantitative calculation model for the scores of each sub-facilities component, sub-facilities system, sub-systems, and overall ancillary facilities, and combining parameters such as component deduction values, quantity coefficients, and preset weights, and formulating a unified technical condition judgment standard of 5 levels (A to E), based on the evaluation methods of this application, it is possible to achieve accurate evaluation of the technical condition of ancillary facilities of long-span bridges from local components to the overall system, providing a scientific quantitative basis for bridge ancillary facility maintenance decisions, ensuring bridge operation safety, and optimizing the allocation of maintenance resources.

Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0021] The method and apparatus for assessing the technical condition of ancillary facilities of long-span bridges in this application is a systematic assessment technology based on hierarchical classification standards, layered quantitative calculation, and unified level determination. It is applied in the field of bridge engineering technology to accurately assess the technical condition of non-structural ancillary facilities of long-span bridges.

[0022] The specific implementation of this application is referred to Figures 1-3 ,like Figure 1The image shows a specific embodiment of the method for assessing the technical condition of ancillary facilities of long-span bridges according to this application. This method includes the following steps: 100. Based on the preset classification standards for ancillary facilities, the components of each sub-facility are tested, and the score of each sub-facility system is obtained through preset calculation rules.

[0023] Specifically, step 100 is the basic data collection and preliminary quantification stage of the assessment. Its core lies in achieving an accurate preliminary judgment of the technical condition of each sub-facilities through clear classification standards and scientific testing and calculation. First, based on pre-set hierarchical classification standards, the ancillary facilities of long-span bridges are precisely divided into four major sub-facilities: protective facilities, traffic facilities, landscaping facilities, and other facilities. Then, according to actual functions and structural characteristics, each sub-facilities are further subdivided into several sub-facilities. For example, protective facilities can be subdivided into isolation piers (barriers), height restriction devices, etc., thus clearly defining the scope of the assessment and avoiding "blind spots" in the actual assessment. Next, using specialized equipment and tools suitable for inspecting the components of the ancillary facilities, the components of each sub-facilities are inspected from multiple dimensions, including appearance, performance, and structural integrity, to comprehensively obtain the original inspection data of the components, such as the degree of damage to sound barriers and the clarity of traffic signs. Finally, the collected component inspection data is substituted into the preset calculation rules, and combined with the basic score of the component itself, the deduction value corresponding to different inspection indicators, the lowest component score in the sub-facility, and the component quantity coefficient, etc., the specific score of each sub-facility system is obtained through formula calculation, providing accurate basic data support for subsequent hierarchical evaluation.

[0024] 200. Calculate the scores of each sub-facility system with the preset sub-facility system weights to obtain the sub-facility system scores.

[0025] Specifically, step 200, based on the sub-facilities system assessment, further integrates upwards to achieve a comprehensive assessment of the technical status of various sub-facilities systems within the entire ancillary facilities system. First, it obtains the pre-defined weight values ​​of each sub-facilities system within its respective ancillary facilities sub-facilities system. These weights are determined by considering the criticality of each sub-facilities system to the bridge's operational safety and functional performance. Then, it multiplies the sub-facilities system score corresponding to each type of sub-facilities system with its corresponding weight. Finally, it sums the weighted scores of all different sub-facilities systems after the multiplication operation to obtain the sub-facilities system score. This score comprehensively reflects the overall technical status of various sub-facilities systems within the ancillary facilities of long-span bridges.

[0026] 300. Calculate the sub-facility system score with the preset sub-facility weight to obtain the overall score of the ancillary facilities.

[0027] Specifically, step 300 is the overall integration stage of the ancillary facility assessment. By weighted summarization of the technical conditions of various sub-facility systems, a quantitative result of the overall technical condition of the ancillary facilities of the long-span bridge is ultimately formed. First, preset sub-facility weight data is retrieved. This weight data is set based on factors such as the importance of the sub-facility system in the ancillary facility system and its impact on the overall bridge operation. For example, protective facilities, because they are directly related to traffic safety, have a higher weight than landscape facilities. Then, the sub-facility system score obtained in step 200 is multiplied by its corresponding sub-facility weight to obtain the weighted score of that sub-facility system in the overall ancillary facility system, thus reflecting the differences in the contribution of different sub-facility systems to the overall condition of the ancillary facilities. Finally, the results of the multiplication of all sub-facility systems are summed to obtain the overall ancillary facility score. This score is the final quantitative representation of the overall technical condition of the ancillary facilities of the long-span bridge, providing a basis for subsequent grade determination.

[0028] 400. By comparing the scores of each sub-facility system, the sub-facility system scores, and the overall scores of the ancillary facilities with the preset technical condition assessment standards, the corresponding level of technical condition is obtained.

[0029] Specifically, step 400 is the final judgment stage of the assessment. By comparing multi-dimensional scores with standards, a clear definition of the technical condition of ancillary facilities at each level, from local to overall, is achieved, providing a clear basis for maintenance decisions. First, the technical condition assessment standards for each sub-facility, sub-facility system, sub-facility system, and ancillary facility are retrieved from the assessment standard database. These standards pre-define score ranges corresponding to five levels (A to E) of technical condition. The score ranges for different levels are set separately according to the functional positioning and assessment needs of each level, ensuring the relevance and rationality of the judgment. Next, the scores of each sub-facility system, sub-facility system, sub-facility system, and the overall score of ancillary facilities obtained in the previous steps are compared one by one with the score ranges in the corresponding level assessment standards. For example, the score of the anti-glare panel (screen) sub-facility system is compared with the A to E level score ranges of the assessment standards to determine its level. Finally, based on the comparison results, the technical condition level of each sub-facility system, sub-facility system, and overall ancillary facility is determined, forming a complete level determination system from the sub-facility to the overall ancillary facility, clearly presenting the problems at each level, and providing clear guidance for subsequent precise maintenance and optimized allocation of maintenance resources.

[0030] Furthermore, such as Figure 1As shown, the technical condition assessment of ancillary facilities for long-span bridges is a progressive process: First, step 100 involves inspecting each sub-facility component according to preset classification standards and calculating the score for each sub-facility system using calculation rules. Then, step 200 involves substituting the sub-facility system weights to calculate the sub-facility system score. Next, step 300 uses the sub-facility weights to calculate the overall score for the ancillary facilities. Finally, step 400 compares the scores of each sub-facility system, sub-facility system, and ancillary facilities with preset standards to determine the corresponding technical condition level.

[0031] In one possible implementation, based on a preset classification standard for ancillary facilities, the components of each sub-facility are inspected, and a score for each sub-facility system is obtained through preset calculation rules. This includes the following steps: According to the preset classification standard, ancillary facilities are precisely divided into four major categories: protective facilities, traffic facilities, landscape facilities, and other facilities. Each sub-facility system is then further subdivided into several sub-facilities. Using inspection equipment and tools, the components of each sub-facility are inspected to obtain component inspection data. This component inspection data is then substituted into the preset calculation rules, combining component scores, inspection index deductions, minimum component scores, and quantity coefficients, according to the formula... and The scores for each sub-facility system were calculated, among which For ancillary facilities i Technical condition rating of sub-facility systems; For the first i Sub-facilities j The rating of each component For the first i Sub-facilities j The deduction value for each component's corresponding testing index; For the first i The lowest score among the components in the sub-facility category; This is a coefficient that varies with the number of components.

[0032] The scores for each sub-facility system are calculated.

[0033] Specifically, the technical condition assessment of ancillary facilities for long-span bridges focuses on non-structural facilities installed to ensure bridge traffic safety. These include sub-systems such as protective facilities, traffic facilities, landscaping facilities, and other facilities, each of which contains several sub-facilities. The classification standards for ancillary facilities of long-span bridges are shown in Table 1.

[0034] Table 1. Classification and Importance Standards of Ancillary Facilities for Long-Span Bridges Specifically, inspection technicians should determine the scores of each sub-facility and sub-facility system based on the inspection results, including the integrity, deterioration trend, and normal operation of each sub-facility system.

[0035] In one possible implementation, calculating the sub-facility system score by multiplying the sub-facility system score with a preset sub-facility system weight includes the following steps: retrieving the weight values ​​of each type of sub-facility in its respective sub-facility system from a preset weight database; multiplying the sub-facility system score with its corresponding sub-facility system weight; summing the results of the multiplication of all sub-facility scores under the same sub-facility, according to the formula... The system scores are obtained by sub-systems, among which Assess the technical condition of the ancillary sub-facilities. The weight of each type of sub-facility within its respective sub-facility system.

[0036] In one possible implementation, calculating the overall score of the ancillary facilities by multiplying the scores of each sub-facility system with preset sub-facility weights includes the following steps: obtaining preset weight data for each sub-facility system in the entire ancillary facility system; multiplying the scores of each sub-facility system with their corresponding sub-facility weights; summing the results of the multiplication operations for all sub-facility systems according to the formula... The overall score for ancillary facilities is obtained, among which Score the overall technical condition of the ancillary facilities. For the first i Technical condition rating of ancillary facilities systems. For the first i The weight of the ancillary sub-facilities system within the entire ancillary facilities.

[0037] In one possible implementation, the technical condition level of the corresponding level is obtained by comparing the scores of each sub-facility system, the sub-facility system, and the overall score of the ancillary facilities with the preset technical condition assessment standards. This includes the following steps: obtaining the technical condition assessment standards for each sub-facility system, the sub-facility system, and the overall ancillary facilities from the assessment standard database; comparing the scores of each sub-facility system, the sub-facility system, and the overall ancillary facilities with the score range of the corresponding level; and determining the corresponding technical condition level of each sub-facility system, the sub-facility system, and the overall ancillary facilities based on the comparison results.

[0038] Furthermore, such as Figure 2As shown, the assessment of the technical condition of ancillary facilities adopts a method from sub-items to the overall assessment. It begins by calculating the scores of each sub-facility system at the start of the process, then assesses the technical condition level of each sub-facility system based on these scores. Next, the sub-facility system score is multiplied by its weight to obtain the sub-facility system score, and its technical condition level is assessed simultaneously. Finally, the sub-facility system score is multiplied by its corresponding weight to obtain the overall score for the ancillary facilities, thereby assessing the overall technical condition level of all ancillary facilities. The entire process is characterized by its progression from partial to overall, with scoring calculation and level assessment proceeding simultaneously: it integrates scores from different levels of facilities through weighted calculations, and directly assigns a level after each level's score calculation, ensuring that the assessment results cover all levels of condition from sub-facility to the overall ancillary facilities.

[0039] Specifically, ① the calculation method for assessing the technical condition of sub-facilities: No. i The technical condition score of the sub-facilities is calculated using the following formula.

[0040] In the formula: For ancillary facilities i Technical condition rating of sub-facilities.

[0041] For the first i Sub-facilities j The rating of each component.

[0042] For the first i Sub-facilities j The deduction values ​​for each component's corresponding testing indicators are shown in Table 2.

[0043] Table 2 Deduction values ​​for each testing indicator of sub-facility components For the first i The component with the lowest score among all sub-facilities.

[0044] The coefficients vary with the number of components, as shown in Table 3.

[0045] Table 3 Parameters t Value table ② Calculation method for assessing the technical condition of sub-facilities: The technical condition score of each facility system is calculated using the following formula.

[0046] In the formula: The technical condition of the sub-facilities is scored.

[0047] The weights of each type of sub-facility within its respective sub-facility system were obtained through an AHP expert questionnaire survey, and the specific values ​​are shown in Table 4.

[0048] Table 4 Weights of Various Ancillary Facilities for Long-Span Bridges ③ Calculation method for overall technical condition assessment of ancillary facilities: The overall technical condition assessment of the ancillary facilities is calculated using the following formula.

[0049] In the formula: Rate the overall technical condition of the ancillary facilities.

[0050] For the first i Technical condition rating of ancillary facilities systems.

[0051] For the first i The weight of the sub-facilities in the entire ancillary facilities system is shown in Table 4.

[0052] The technical condition of ancillary facilities and sub-facilities should be scored based on the technical condition of the sub-facilities. Determined. The technical condition of each facility system should be scored based on the technical condition of the individual facility systems. Determined. The overall technical condition of the ancillary facilities should be based on the ancillary facilities overall technical condition index. Confirmed. The technical condition is divided into 5 levels, and the criteria and thresholds for judging the levels are specified in Table 5.

[0053] Table 5. Technical Condition Assessment Standards for Ancillary Facilities of Long-Span Bridges One possible implementation also includes the following steps: establishing a dedicated database to store the testing data of each sub-facility component, the data of the scoring process at each level, and the final evaluation result data; classifying and organizing the stored data; setting index tags to facilitate subsequent queries and retrieval; and regularly backing up the database to ensure data security and integrity and prevent data loss.

[0054] This application also provides a technical condition assessment device 100 for ancillary facilities of long-span bridges, comprising: The detection data acquisition module 110 is equipped with a variety of devices adapted to the detection of components of long-span bridge ancillary facilities, used to acquire raw component detection data.

[0055] Specifically, the data acquisition module 110 plays a crucial role in acquiring fundamental data within the entire evaluation system. This module is equipped with various specialized devices for inspecting the components of long-span bridge ancillary facilities, such as high-resolution image acquisition equipment capable of clearly recording surface damage and corrosion. It also includes various sensors, such as laser displacement sensors for measuring displacement, which accurately acquire dynamic data of various ancillary facilities (such as sound barriers) under strong winds. These devices work together to comprehensively inspect the components of the ancillary facilities from multiple dimensions, thereby obtaining raw component inspection data to support subsequent evaluation processes.

[0056] The calculation and processing module 120 is used to receive the component inspection data transmitted from the inspection data acquisition module 110, calculate the score of each sub-facility system according to the preset rules, and then perform subsequent score calculations at each level in combination with the weights, and finally complete the determination of the technical condition level at each level and output the evaluation results.

[0057] Specifically, the calculation and processing module 120 is the core computing unit of the entire evaluation device. After the detection data acquisition module 110 completes data acquisition, it transmits the raw component detection data to the calculation and processing module 120 in real time. The calculation and processing module 120 has a series of complex calculation rules pre-stored. Upon receiving the data, it first performs preliminary processing on the component detection data according to these rules, calculating the score of each sub-facility system. Then, the module calls the preset sub-facility weight data and calculates the scores of each sub-facility system to obtain the sub-facility system score. Next, it uses the preset sub-facility weights to calculate the sub-facility system score to obtain the overall score of the auxiliary facilities. Furthermore, the calculation and processing module 120 compares the scores of each level with pre-set technical condition evaluation standards to determine the technical condition level of the corresponding level, ultimately outputting a complete evaluation result to provide a quantitative basis for subsequent maintenance decisions.

[0058] The data storage management module 130 establishes a dedicated database to store the detection data of each sub-facility component acquired by the detection data acquisition module 110, the data generated by the calculation and processing module 120 during the scoring process at each level, and the final evaluation result data.

[0059] Specifically, the data storage management module 130 is responsible for the data storage and management of the entire evaluation device. This module establishes a dedicated database to store various types of data generated during the evaluation process. When the detection data acquisition module 110 acquires the detection data of each sub-facility component, it promptly transmits this raw data to the data storage management module 130. The module then accurately stores this data in the database according to predetermined data storage formats and classification rules for subsequent querying and retrieval. During the calculation and processing module 120's calculation of scores at each level, the intermediate data generated, as well as the final scores and evaluation results, are also collected and stored by the data storage management module 130. Furthermore, this module possesses efficient data management functions, capable of organizing and backing up stored data, and supporting rapid data retrieval. This allows staff to easily access the required data at any time, ensuring the integrity and security of the evaluation data, and providing strong support for the long-term conduct of the evaluation work and historical data comparison and analysis.

[0060] Furthermore, based on the same inventive concept, this application also provides a technical condition assessment device 100 for long-span bridge ancillary facilities, such as... Figure 3 As shown, this long-span bridge ancillary facility technical condition assessment device 100 comprises three core modules: First, the detection data acquisition module 110 consists of a detection equipment integration unit 111 and a data preliminary processing and transmission unit 112. The detection equipment integration unit 111 has built-in adapted detection equipment to acquire raw data of the components, while the data preliminary processing and transmission unit 112 is responsible for processing and transmitting the data. Next is the calculation and processing module 120, under which the hierarchical classification calculation unit 121, the sub-facility system score calculation unit 122, the hierarchical summary calculation unit 123, and the level determination unit 124 work in sequence to receive the collected data, calculate the scores of each level according to the rules, and determine the technical condition level. Finally, the data storage and management module 130 is responsible for storing the detection data, intermediate calculation data, and final assessment results throughout the entire process.

[0061] In one possible implementation, the detection data acquisition module 110 includes: a detection equipment integration unit 111, used to organically integrate various detection devices; and a data preliminary processing and transmission unit 112, used to perform structured processing on the raw detection data acquired by the detection equipment, that is, to package it according to a specific data format, and then transmit the processed data quickly and stably to the computing processing module 120 through a wired or wireless data transmission channel.

[0062] In one possible implementation, the calculation processing module 120 includes: a hierarchical classification calculation unit 121, which classifies ancillary facilities into four major categories—protective facilities, traffic facilities, landscape facilities, and other facilities—based on a preset hierarchical classification standard, and further subdivides these into several sub-facilities; a sub-facility system score calculation unit 122, which receives component inspection data from the inspection data acquisition module 110, and calculates the score of each sub-facility system according to preset calculation rules, combining component scores, inspection index deduction values, minimum component scores, and quantity coefficients; and a hierarchical summary calculation unit 123, which first multiplies the score of each sub-facility system with the preset weights of each sub-facility, and sums the calculation results of all sub-facilities under the same sub-facility to obtain the sub-facility system score, and then multiplies the sub-facility system score with the preset sub-facility weights and sums them to obtain the overall score of the ancillary facilities. The rating unit 124 retrieves the overall technical condition assessment standards for each sub-facility system, sub-facility system, and auxiliary facilities from the assessment standard database, compares the scores of each level with the corresponding score ranges, and determines the technical condition level corresponding to each level based on the comparison results.

[0063] The method and apparatus for assessing the technical condition of ancillary facilities of long-span bridges proposed in this application can clearly define the assessment boundaries by pre-setting a hierarchical classification standard of "sub-facility components – sub-facility systems – sub-facility systems – overall ancillary facilities". Combined with component data collected by testing equipment, the scores of each level of "each sub-facility component, sub-facility system, sub-facility system and overall ancillary facilities" are calculated according to a quantitative formula. The level is then determined by comparing with the 5-level (A to E) assessment standard, and the data is stored and managed through a dedicated database. This solves the problems of vague assessment scope, subjective scoring and coarse grading in traditional assessments, and achieves accurate assessment from local components to the overall system. It provides a scientific quantitative basis for ancillary facility maintenance decisions, and ensures the safety of bridge operation and optimizes the allocation of maintenance resources.

[0064] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
